Figure 5 is an enlarged, partial cross sectional View taken substantially along the line '5-5 of Fig. 1; and y Figure 6 is a partial cross sectional view taken substantially along the line 6-6 of Fig.,1.

Referring to Figs. 1 and 2 of the drawings, the preferred embodiment there illustrated is shown adapted for operating a rear quarter panel Window I0 of a convertible coup model automobile. The regulator includes a triangular shaped bracket l2 supported along one side thereof on the pillar I4 of the body I6, and secured thereto by a plurality of bolts ll and cage nuts I8. A plate 20 formed to provide a hub 2| thereon, is spot welded to the triangular bracket rI2 adjacent one corner thereof. A supporting member 22 is pivotally mounted on the hub 2l and secured to the plate 20 by a shoulder pin 24 which receives a washer 26 and a nut 28 onv its outer end. The nut 28 is pinned to the bolt 24 by acotter pin 30.- As best shown by Fig. 4, a channel 32 is secured to the supporting member 22 by a plurality of bolts 34, and is disposed horizontally above the hub upon which the member 22 is pivotally mounted, when the window lis in the closed position. The forward portion of thelower side of the window channel 36 rests on the upper edge of the channel 32 and is secured to the supporting member 22 by v a plurality of screws 38. The'window. channel 36 supports the window I0 in the rubber channel mounting 40.

The bolts 34, which secure the channel 32 to one side of the supporting member 22, extend through the member 22 to engage a gear segment 42 and secure it to the other side of the member 22. Below the' channel 32 the gear segment 42 is secured to the member 22 by bolts 44, as seen in Figs. `1 and 2.

Still referring to Figs. 1 and 2, a bell crank 46 has its apex pivotally supported on the triangular bracket I2 rearwardly of the hub plate 20 by the pivot pin 48. The inner end of the pin 48 is mounted flush with the surface of the bell crank and the other end is bifurcated to `receive one end of a coil counterbalance spring 50, the other endI of which is anchoredin the bracket l2.

` One end of the bell crank 46 comprises a gear sector 52 which extends generally horizontally toward the-hub 2| and engages the gear segment 42. The radii of the gear segment 42 and the gear sector 52 lare so proportioned that Aa relatively small angular movement of the sector 52 Aproduces Referring to Figs. 1, 3V and 5, and particularly to Fig. 3, a channel 62 serves as a frame or sup-` porting member for the nut and screw means referred to above, and is secured at itsforwa-rd end to the body pillar I4 by an angle bracket 64.

The bracket 64 is spot weldedto the pillar I4" and is connected to the channel 62 by a bolt 66. At a point spaced from its other end, the channel 62 is mounted on another body pillar 68 by a bracket 10 which is similar to the bracket 64 'and has one leg spot weldedA to the pillar 68 and the `other le'gfconnected to the channel 62 by bolts 12. An electric motor 141s mounted on the chan- 1161.62 adjacent the rear end thereof by a bracket 16'whichis spot welded to" the channel 62 and secured toA the motor 14/by bolts 18. y

The. shaft 80of the motor 14 is connected to an'elongatedscrew shaft 82 by'mean's of a coil spring` V84 which affordsa spring drive between the motor'14 and? the shaft 82. T he shaft 82 is universally mounted at' both ends in spherical balls. 852 havingfa bore extending therethrough adapted' to" receive the shaft 82. The ball-86 adjacentthedriven-end of theshaft s2 is mountedin twoliemisphercal'elements 88 having outwardly'exten'ding"flanges secured together by a 2 plurality of'rivets 90.4 One' of the'hemispherical elements 8*'8'hask a bracket portion 92 integrally formed thereon, one end ofl which is secured to bieIfiQtl 'Mfby the bolts 18. The ball 35 at the forwardendv Qfj'the shaft 8`2is similarly mounted apair of hemispherical; elements 94 similarly heldV together by rivets 9 8` and one of said elements'QL. has a bracket portion 08 integrally formed thereorrwhich is spot welded to the channel; 62,. may beA s eenlv in Fig. 6, the nut is threadedly" received on the screwshaft 82and is provided; with opposed'boss portions |00- and |02 adaptedo coo.perate with the-bifurcated portions Ejkandf 58' cfgthe'army 5 4 on the bell crank 46. 'lhefball 8,6,which universally supports the'forward end of the sha-ft 82. also serves as a thrust bearing-to prevent'axial movement of the screw shaft, 32.Y Asbest shown inFig. 3, a shoulder H6 integrally formed on the shaft 82 engages thegbalvl; 86 to prevent axial; movement of said s h ft-in onev direction, and a disc I I8 mounted onitbe end-"oiV the-shaft by a bolt |20 engages saidfgbaw-ll; 86 to preventl movement of the screw shaft 825m the opposite, direction.

'1f-heA motor 1 4 isconnected tothe electrical system of the automobile by wires |03 (Fig. 1');

ovfjwhichfpower maybe suppliedto the motor to runitiineither direction;

Referring; again t o Figs. 1,3 and 5..an;arcuate channel shaped-guideqrack- |04 is disposedin the plane off theV window Ilandaconcentric'with the hub2| YwithV the open side` thereof presenting I non ofithe window channeias ofthe window |10 through acontrol switch (not shown)` by means as the window is pivoted from the closed to the open position. The inwardly presenting edges |06 and |08 of the guide rack |04 are adapted to engage a roller |I0 carried by a bracket ||2 mounted on the frame 35 of the window I0. The roller ||0 is provided with anges |I4 at either end thereof adapted to receive the guide rack |04 therebetween andfengagefthefopposed external surfaces thereof to prevent lateral movement of the roller I I0 and hence the window I0, relative to the guide rack |04.

It will now be appreciated that, by removing the screw |05 and the bolts 66 and 12, the channel 62 andthe entire nut and screw drive means mounted thereon, may be readily removed as a unit.

The operation of the above described window regulator is as'follows. Commencing with the windowv I0 in the closed position illustrated in Figure 1, the control switch is turned to apply electrical power to theV motor 14and turn itY in an opening.- direction. The motor 14 through its shaft and the spring 84 drives the screw shaft 82 ina directiony to cause the. nut 60 mounted on the screw shaft 82 to move rearwardly along the shaft 82er to the right as viewedin-Figure 1. This travel.v of? the nut 60, through its engagement withV the bifurcated end portions 56 and 58 of thebell crank 46, causes the gear sector 52 topivot in a counterclockwise; direction and drive the gear segment 42 in a clockwise direction. In this manner the glass I0, which. is mounted on--the samesupporting member 22 upon which; carries; the geary sector 42: is rotated in a clockwise direction aboutY the huby 2| in an open direction. This movement -maybe continued untilv the window I0 reaches thevposition indicated in broken lines in- Figure 1A inwhich the frame 36V abuts against arubber'stopper |22 mounted on theA pillar |4` by bracket |24,v at which time the window I0 has lpivoted through an' angle of and" is then'inthe fully openedposition. It will -be understood that the window may be closed by turning the;` control switch' to a position in which power' is supplied. to themotor 14 to drive it in the oppositedirection and thus reverse the above described. operation.

Although: only one formfof the invention has been illustrated-and described inv detail; it will be apparent to those skilled in the art thatvarious modications may `be'made without departing from' thev scope-of the claims.
